Preparation and enhanced electrical breakdown strength of PVDF-TrFE-CTFE/PVDF-HFP film composites

Preparation, Characterization, Thermal and Electrical Conductivity Properties of PVDF Composites

Using PVDF and ZrO2, polymer composites were prepared by sol gel method. Various measurements such as X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Differential Scanning Calorimetry (DSC) were used to characterize the composites. Thermal and electrical properties of the composite samples were studied. The conductivity of composites was found to increase with increase in temper...

Liquid-phase tuning of porous PVDF-TrFE film on flexible substrate for energy harvesting

PVDF-HFP/PVC Blend Based Lithium Ion Conducting Polymer Electrolytes

Abstract. Flexible free standing polymer electrolyte films have been successfully prepared using a blend of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and poly(vinyl chloride) (PVC) doped with lithium perchlorate (LiClO4). The conductivity of the film was influenced by salt concentration and the degree of crystallinity. An optimum room temperature conductivity obtained was 2.10...

Novel PVDF-HFP membranes tailored by supercritical drying ..

The work is based on the drying of PVDF-HFP gels with a procedure assisted by supercritical CO2 to obtain nano-sized porous membranes at high quality/low cost ratio. Poly(vinylidene fluoride) (PVDF) as homopolymer or copolymer with hexafluoropropylene (PVDF-HFP) is a very interesting material largely used in catalytic membrane reactors, chemical and biomedical applications and various filtratio...

Cold-field switching in PVDF-TrFE ferroelectric polymer nanomesas.

Polarization reversal in ferroelectric nanomesas of polyvinylidene fluoride with trifluoroethylene has been probed by ultrahigh vacuum piezoresponse force microscopy in a wide temperature range from 89 to 326 K. In dramatic contrast to the macroscopic data, the piezoresponse force microscopy local switching was nonthermally activated and, at the same time, occurring at electric fields significa...
